SPECIFICATION forming part Of Letters Patent NO. 602,445, dated April19, 1898. Application filed March 14, 1894. serial No. 503,541. (Nomodel.)

To ctZZ whom, it 772/611] concern.-

Be known that I, PAUL HANSON, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventednew and useful Improvements in Grain-Binders, of which the following isa specification.

This invention relates to grain-binders, and particularly to thetripping and compressing mechanisms; and its objects are to simplify andcheapen the construction of the same, to render it more effective inoperation, and to adapt it to a wider range of use.

IVith these objects in view the invention consists in the construction,combinations, locations, and relative arrangements of parts, as morefully hereinafter described, as shown in the accompanying drawings, andas finally pointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation of the end orbinder deck side of a grain-binding machine, taken from the stubble sideof the machine. Fig. 2 is an end view of the construction shown inFig. 1. Fig. 3 is a plan View, on an enlarged scale, showing thearrangement of my invention. Fig. 4 is a view in side elevation of the0011- struction shown in Fig. 3 and showing in dotted lines adisplacement of the parts from their position as shown in full lines.Figs. 5, 6, 7, and 8 are detached detail views of various parts of myinvention.

Referring to the drawings and to the various views and reference signsappearing thereon, and wherein similar reference signs refer to anddesignate similar parts wherever they occur throughout the severalviews, 1 designates the side plates or framework of the elevators, 2 themaster-wheel,and 3 the framework, of a harvesting-machine.

Supported by the framework of the machine is the housing or framework 4,in which are suitably journaled the needle-shaft 5, theknotter-operating shaft 6, and packer-shaft 7, said packer-shaft andneedle-shaft being arranged, preferably, in substantially the samehorizontal plane or as nearly in the same horizontal plane as may be.Intermittent rotary motion is transmitted from the packer-shaft to theknotter-operating and needle shafts by the following-describedmechanism:

Upon packer-shaft 7 is mounted a gear 10,

adapted to mesh with a gear 9 upon an intermediate shaft 8. Thisintermediate shaft carries a sprocket-wheel 11. A correspondingsprocket-wheel 12 is mounted on the knotteroperating shaft 6, and asprocket-chain 13 connects said sprocket-wheels. Rotary motion istransmitted from the knotter-operating shaft to the needle-shaft bymeans of a pitman 15 and crank-arm 16 in the usual way. An idler 14serves to keep sprocket-chain 13 taut. Upon a stud 18, (see Fig. 7,)which is secured in the hub of gear 10, is pivoted the drive-dog 19. Aspiral spring 22 rests at one end against lug 21 on gear 10 and at theother end against lug on the drive-dog and is held in place by pins orprojections, as shown. This spring tends to rock the drive-dog upon itssupporting-stud and thus throw the flange or projection 23 thereon intothe path of the rollers 24 24, carried by the continuously-rotatedpacker-shaft 7, as fully set forth in my Patent No. 510,174, grantedDecember 5,1893.

The upper end of the drive-dog is adapted to be normally engaged by theend 26 of the tripfinger 27, whereby said dog is rocked in a directionopposed to the action of the spring to compress it, and thus hold theflange 23 out of the path of the rotation of the rollers 24 24. Trip 27is pivoted, as at 28, in a lug 29, cast on the usual housing orframework 4, and is provided with lugs 30 31, secured to said tripleveror cast therewith. A rod or bolt 32 is pivoted in lug 30 and passesthrough a perforation in a lug 33, formed on housing or framework 4. Aspiral spring 34 is coiled around bolt 32 and bears at one end againstsaid lug 33 and at the other end against a nut 35, screwed on thethreaded outer end of the bolt 32. By adjusting nut 35 the'tension ofspring 34 can be adjusted. The tendency of spring 34 is to keep the end26 of the triplever normally in position to engage the upper end ofdrive-dog 19, and by adjusting the tension of spring 34 the forcerequired to overcome the action of the spring can 'be regulated, thusgaging the size of the bundle of grain. In order to provide a furthermeans for regulating the size of the bundle, I provide a supplementaryor auxiliary trip-finger 36, adapted to be attached, as at 37, to thetrip-finger 27 between flanges 38 38, formed thereon, which preventlateral movement of said auxiliary finger, as will be readilyunderstood. Upon the hub of the needle-arm is formed a cam 39. This camis adapted to engage at the proper time in its rotation lug 31, formedon trip-lever 27, and thus keep the end 26 thereof elevated out of thepath of drive-dog 19. Cam 39 is so formed that the end 26 is keptelevated a sufficient length of time for the various parts affected bythe rotation of shafts 7 and 8 to perform their work. The operation ofthis part of my invention is as follows, the parts being in the positionshown in Fig. 4:

The grain is fed down the binder-deck 59 and against compressor-hook toform a bundle. When a sufficient quantityhas been fed thereto, thetrip-lever 27 isoperated-thereby by being tilted upon its pivotalsupport 28, thus elevating the rear end thereof out of engagement withthe upper end of drive-dog 19. This movement is opposed by spring 34,which constantly tends to maintain le er 26 in position to engage saiddog. The elevation of lever 26 causes said dog 19 to be tilted upon itspivotal support until flange 23 is in position to be engaged by one orthe other of rollers 24 24, thus causing the rotation of .gear 10, andconsequently gear 9, intermediate shaft 8, knotter-operating shaft 6.,and needle-shaft 5. During the rotation of these shafts the bundle ofgrain is compressed, tied, and ejected from the machine. As needle-shaft5 begins to rotate cam'39 comes into position to engage lug 31 andprevents arm 26 from descending into position to again. lock-drive-dog19 until a complete oscillation; of the needle-shaft has been effectedand the needle has returned to its normal positioni and the bundleejected.

When these oper-.

ations have been completed, the part of cam; 39 is reached where spring34 operates to; force bar 26 into position to lock drive-dog 19? formfurther rotation.

Reference-si n 4O desi nates the com-i s Thls hook is secured in slotpressor-hook.

41 of compressor-bar 42, whereby it may be" adjusted to regulate thesize of the bundle of; grain. Compressor-bar 42 is carried by.com-'pressor-shaft 43, journaled to rock in lugs 44: 44, caston housing 4, orthe compressor-bar: may be pivoted concentric with the needleshaft, aswill be obvious to any one skilled in the art. To the outer free end ofthe compressor-bar is pivoted an internally-scree threaded sleeve 45,adapted to receive the screw-threaded end of a preferably-squared bolt46, adapted to pass through a perfora.

tion in the end of a rock-lever 47, sleeved on binder-pipe 48. A spring49 is coiled-around bolt 46 and bears at one end against the perforatedend of the rock-lever 47 and at the other end against a collar on sleeve45. The.

tied into a bundle. The spring 49 keeps said hook elevated against ayielding resistance, and by screwing bolt 46 into and out of itsthreaded socket the tension of the spring can be regulated, and also theelevation of compressor-hook 40 may thus be regulated. Thus anadditional adjustment is provided for the regulation of the size of thebundle. An arm 50 is formed on or carried by the other end of thesleeve, forming the hub of arm 47, and the free end of said arm isadapted to be projected into the path of rotation of a cam-flange 52,carried by wheel 53, mounted to rotate upon a stud or bolt 54. Thiswheel may be rotated in any suitable way. In the form shown this is astar-wheel, and mounted upon the face of gear 9 are pins 55, adaptedwhen said gear is rotated to enter the space between the points of thestar of starwheel 53 (see Fig. 6) and rotate the said star-wheel step bystep. The part 57 of the points of the star-shaped wheel is adapted toslide against the flanged hub 56 of gear 9, and thus hold the samelocked against further rotation until again operated by studs 55 55. Theoperation of this part of my invention is as follows: The parts being inthe position shown in Fig. 4, except that the end 26 of triplever 27 iselevated, thus permitting rotary motion to be imparted to gear 10, andconsequently to gear 9 and the knotter-operating and needle shafts, asgear 9 rotates in the direction of the arrow, Fig. 4, the lower pin orstud 55, projecting from the face thereof, enters a space in gear 53 androtates it one step. In the positionshown cam-flange 52is in engagementwith a flange 58, Fig. 6, upon rockarm 50, thus holding the arm 47raised, and consequentlythe compressor-bar 42 and hook 40aresolidlysupported against a yielding resistance due to spring 49. The furtherrotation of gear 53 causes cam-flange 52 toride over the friction-rolleron the end of arm 50,

thus rotating the parts above mentioned to their extremeelevatedposition. During this time the bundle of grain is being formedand compressed against compressor-hook 40, .and consequently thegreatest pressure is being exerted against said hook during the latterpart of the engagement of the cam-flange 52 with arm 50that is, whilethe knot is being tied. When cam-wheel 53 is rotated until the end ofthe cam-flange rides off of the end of arm 50, said arm is permitted torise, thus permitting the rock-lever 47, compressor-bar 42, andcompressor-hook 40 to fall into .the position shown in dotted lines,Fig. 4, until the upper end of the compressor-bar 4O falls below thesurface '59 of the binder-deck, thus permitting the bundle to be ejectedfrom the machine. Further rotation ofgear'53 brings the cam flange 52again in contact with flanged arm 50 and again elevates thecompressor-hook 40 into position to assist in compressing another bundleof grain. The relative sizes of gears 9 and 12 are so proportioned thatit requires three rotations of gear 9 to effect a complete revolution ofthe knot-terdriving shaft, and hence of the needle-shaft. It isconsequently essential that gear 53 be given only one completerevolution during a complete revolution of the knotter-operating shaftin order that the operation above described will take place once duringeach complete revolution of said shaft, and while I have described aspecific form of gearing for rotating the gear 53 once during theserevolutions of gear 9 I do not desire to be limited thereto, as manyother forms of mechanism may be employed whereby the same result may beaccomplished.

In order to support the housing or framework carrying theabove-described mechanisms in such manner as to permit of longitudinaladjustment thereof, I provide a pivoted or hinged bracket 60, providedwith pintles 61 62, adapted to be received in suitable perforations orsockets in framework 3 of the harvester-machine. The outer portion ofhousing 4: is provided with a saddle 63, adapted to rest on the outerportion of the upper or horizontal leg of the hinged bracket. The spacein said saddle to receive the bracket is made of sufficient size topermit a relative movement of the housing and bracket, so that when saidhousing is adjusted longitudinally along its support on the framework 3the bracket will be permitted to rock upon its pivots 61 62. Oneimportant advantage attained by the provision of this bracket aside fromits simplicity, cheapness, and efficiency is that the binder-pipe 5L8may be considerably shortened, thus reducing the cost and weight of theattachment. Many other advantages are secured by this construction,which will be readily understood and perceived by persons skilled in theart.

In order to guide and steady the housing 4 in its longitudinaladjustment upon framework 3, the cross-bars or sills 64 are formed tofit flanged bar 66, (see Fig. 8,) and a capplate 65 assists in forming aguide for said flanged bar, as will be readily understood.

It is important that the moment end 26 of the trip-lever engages theupper end of drivedog 19 to throw the flange 23 thereof out of the pathof travel of rollers 24 24 on the packeroperating shaft 7 the reverserotation of gear 10 be avoided in order to lock the train of gearingdriven thereby against retrograde movement. It will be readilyunderstood that by arresting the rotation of trip-dog 19 the action ofspring 22 will be to rotate the gear 10 in a reverse direction throughits engagement with lug 21. In order to avoid this difficulty, I providethe following-described stop or looking devices: Upon cross-bar or sill67 I pivot a dog or trip 68 intermediate its ends. A spring 69 isprovided to bear against one end thereof to keep the same elevated (seeFig. 4) and which normally keeps the other end of said dog depressed.This dog is pivoted to cross-bar or sill 67, adjacent to the bearing forthe end of the packer-operating shaft and adjacent to'gear 10, mountedon said shaft. Said gear is provided with a projection or rib 70, whichin the form shown is formed by eX- tending rearwardly a tooth thereof.(See Fig. 3.) This projection rotates in a path ,to engage and lift theouter end of dog 68 against the action of spring 69; but when drive-dog19 is locked by lever 26 against further rotation, and consequently whenthe rotation of gear 10 ceases, the front end of dog 68 falls intoposition behind the projection 70 and effects a locking of said gearagainst a reverse or retrograde movement.

To limit the rocking of compressor-bar 42, said bar is provided withprojections 71 72, adapted to strike the hub of the needle-arm, or itmay be constructed to strike a portion of the main frame or housing4when the extreme limit of movement of the compressorhook is reached inthe direction in which it may be rocked.

Many changes may be made in the details of construction of my inventionwithout departing from the spirit or scope thereof, and I do not desireto be limited to the exact and specific details shown and described; but
